Scientists in South Africa discovered during experiments with a synthetic mutated virus developed in a laboratory, similar to the South African strain of SARS-CoV-2, that it was able to withstand antibodies.
The journal Nature Medicine published the results of research by scientists from the South African Health Care Agency’s National Institute for Infectious Diseases, which they conducted in collaboration with scientists from other institutions in the country.
The researchers compared the containment of the 501 YV (South African) strain of the Corona virus and the original version of the virus with three classes of antibodies, and came to the conclusion that the bodies succeeded in containing the original virus, but not the mutated strain.
Then the two copies were tested with the plasma of the 44 people heading for recovery, and they were transferred to Johannesburg hospitals. Half of the plasma samples did not show any anti-501 YV activity, while another part showed a weak reaction, and only 3 samples showed high efficacy.
The researchers pointed out that the antibodies were able to guarantee only partial protection, which indicates a high probability of repeated infection with the mutated strain of the Corona virus, and the need to continue research in the field of basic materials for vaccines, as the materials that make antibodies by binding to protein S, are Effective against new mutated versions of the Coronavirus.
